8 Claims.

This application is a division of the copending application Serial No.489,145, filed October 16, 1930, Patent 1,976,585 October 9, 1934.

This invention relates to a money delivering device in which themembers, controlling the selective ejection of the different sorts ofcoins are controlled by perforated cards and consists in the provisionof a common operating member and means for automatically rendering thelatter operative by the presence of a card so as to cause the automaticoperation of the card feelers and the coin ejecting control members ofthe coin disbursement device. In view of such provision the operation ofthe machine is considerably simplified and as its speed of operation isincreased the efficiency of the machine is correspondingly increased.

In the, present invention it is immaterial whether perforated cards areused for controlling the coin disbursement device as the perforatedcards may be replaced by equivalent arrangements, such as perforatedstrips, cards or plates with, registration indicating points, and. thelike. Further, the manner of repre- 2 senting values by perforations orregistration indicatingpoints of the cards or the like is quiteimmaterial to carry out the present invention. ,In the constructionalexample hereinafter described a perforated card is used in which eachnumerical value is represented by a corresponding number of successiveholes arranged in a common row.

A device constructed according to the present invention is illustratedby way of example on 35 the accompanying sheet of drawings in which:-

Fig. l is a diagrammatic sectional View of the machine showing themachine in a normal position and Fig. 2 a similar view showing themachine in a partially operated position.

- Fig. 3 is'a detail view, 7

Fig. 4 shows a part of the perforated card and Fig. 5 is a sectionalview taken on the line 5-5 of Fig. 1.

Several rows of feelers 2, corresponding in number to the kinds of coinsto be paid out, are arranged in a casing I. Each row of feelers, relatedto a certain sort of coin, comprises nine pins. Springs 3, (Fig. 1)arranged 50 on the feelers, force the latter through a slid- .ablymovable plate 4, which is provided with holes through which said feelersmay project.

By means of a pin 1 coacting with an angular slot 6 of a plate 5, it ispossible to move the "55 plate 4 for a purpose that will later beevident.

In Austria October 19, 1929 A second plate 8, provided with holes, issecured opposite the plate 4 and. likewise, has holes through which thefeelers may project. The topend of both plates are bent away from eachother and thus provide outside of the casing I a funnel 21 for theinsertion of the card. The feelers of a single row are angularlydisposed in a vertical plane in such a manner that their right ends maylimit the upward movement of a coin ejector 9. The latter consists of alever which is provided with a longitudinal slot and is first slidableand then rotatable on a pin Ill engaging said slot and fixed to anoperating lever II. A spring l2 tends to retain the pin 10 in the bottomend of thelongitudinal slot of the coin ejector lever 9. Further, thelower end of the coin ejector 9 has a pin and slot connection to a lever13, which in conjunction with a lever l4, fixedly pivoted at one end,forms a toggle lever. A lever l5, pivoted to the joining pivots of thelevers l3-|4 is provided with a slotted and through which slot passes apin 16 fixed to the operating lever H. A spring ll tends to turn theoperating lever II in a clockwise direction about its pivot I8 so as toreturn it to its normal position shown in Fig. 1 after having beenoperated as shown in Fig. 2.

A slotted plate 20, (see Fig. 3) which forms a support for the coinsinserted in the tube 2 I, is arranged opposite the hammer-shaped top endof the coin ejector 9 (Fig. 1). A sleeve or tube 22 slides on the tube2! and rests on the top edge of the coin ejector. A funnel 23 is locatedopposite the coins of e a related stack and in connection with thecorresponding funnels for the other sorts of coins they all terminaitein a common collecting funnel 24, underneath of which is placed, forinstance, a wagereceiving bag 25.

The device operates in the following manner:--

The perforated card 26 is inserted, reversed with respect to theposition shown in Fig. 4, through the card insertion funnel 21 of thecasing I until its top edge (which now faces downward) engages with thecenter partition la of the casing. In this position the holes of thecard are disposed opposite the feelers 2. For instance, if according tothe card shown in Fig. 4 the sum of $26.23 is to be paid out, and if thegroup of feelers shown in the drawing serves for selecting the dollarunits, the six holes in the card will be disposed opposite the six lowerfeelers 2. When the operating lever H is rocked counterclockwise bymeans to be subsequently described, the plate 5 moves downwardly to theFig. 2 position and by the provision of the angular slot 6 the pin 1,and thus the plate 4, are shifted to the left. The plate 4 releases thefeelers 2 so that, by the action of the springs 3, the feelers movetoward the card and at the places where they find holes in p the cardthe feelers pass through the same. In the present case the six bottomfeelers pass through the card, while the three top feelers engage theface. of the card as shown in Fig. 2.

During the further counterclockwise operation of the lever i i, the coinejector 9 by means of the spring 12 is elevatedsofar as is permitted bythe six feelers which have been'withdrawn from its path of movement. Thecoin ejector is positively stopped by the seventh feeler. During thelast phase of the counterclockwise movement of the lever H beyond. theFig. 2 position the pin it cooperates with the top end of the slot inthe lever l5 and forces upward the joining pivot of the two levers l3and I4. Thereby, the coin ejector 9 rocks about the pin I and shifts sixof the oppositely lying dollar coins into the funnel 23. After thisoperation is performed the lever II is returned to its initial positionby the spring I1. Now the joining pivot of the toggle lever l3, I4 isdepressed by the pin I6 as shown in Fig. 1 and the coin ejector returnsto its normal position. At the same time the coin ejector is moveddownwardly so that the coins in the tube 2! resting on the ejector 9 canslide down until they are stopped by the plate 2!]. Owing to the weightof the sleeve or tube 22 it participates in the downward movement of thecoin ejector, so that the unwanted coins are protected againstaccidental dropping into the funnel 23. During the last phase of thereturn movement of lever II the plate 4 is shifted to the right by thereverse action of cam slot 6 on the pin 1 and thereby the feelers areforced out of the perforated card to the position shown in Fig. 1 andthe latter can now be freely removed by the operator.

A feature of the present invention consists in causing the automaticoperation of the operating member by the insertion of the card in themachine. This object may be attained for instance by providing aseparate feeler, which is shifted from its position of rest whenever acard is properly disposed for registration with the feelers, and therebyrenders operative automatically the feelers and the coin disbursementdevice.

When a card 26 is inserted in the machine to engage with the centerpartition la the said card cooperates with card actuated lever 28,

which is in frictional contact (see Fig. with a contact lever 29. Cardactuated lever 28 is moved from the position shown in Fig. 1 to theposition shown in Fig. 2 and shifts the contact lever 29 from itsposition shown in Fig. 1 to its position shown in Fig. 2 to closecontacts 38 when the card is in the position shown in Fig. 2. Therebycurrent passes through the magnet 3|, which attracts the lever H andmoves it in a counterclockwise direction. The latter, as previouslydescribed, causes the cooperation of the feelers with the card and theejection of the desired coins. During the last phase of thecounterclockwise movement of lever II an extension 32 of the lever Hstrikes against the contact lever 29, shifts it independently of thecard'actuated lever 28 which is held in rocked position (Fig. 2) by thecard to the position shown in Fig. 1 and against a pin 29a, and thusopens the contacts 30. In view thereof, the magnet 3| becomescurrentless and the lever H returns into the initial position by theaction of the spring l1. When the card is manually removed from themachine by the operator the lever 28 is returned to its initial position(shown in Fig. 1) by a spring 33 but lever 29 is prevented from movingby the pin 29a. The machine is now ready for the reception of the nextcard and the operation can be repeated.

Of course the number of the coin magazines and groups of feelers dependson the kinds of coins to be ejected by the machine. In the illustrativeembodiment the vertical rows of feelers are arranged in such a mannerthat at their left they are separated from one another a distanceequivalent to the vertical spacing of the rows of holes in the card,while their right ends are vertically separated from one another adistance equivalent to the separation of the coin magazines.
